even am a AMD fan..but after using this sytem of my friend i feel the intel is a bit morefaster..
check out the d102ggc2 mobo in the intel site.. it support PIV,PD and Celeron.. so u can change proccy later too..
*www.intel.com/products/motherboard/d102ggc2/index.htm
the board will cost u about 5K and the procc u choose.. the PIV 3.2 800mhz FSB is about 5500 so it comes to 10500 or 11K max.. then this has a inbuilt ati radeon X300 64 MB shared,DDR2 is also supported and it has a PCI-Express slot.. 16X.. the price of 7600 GS 256MB is about 6K or the Ati Radeon X1600 Pro PCI-E 512 Mb which is 6900 u can say 7K..
